Patented Sept. 5, 1939 UNITED STATES PATENT OFFICE Jean Marie JosephPlasse, El Hajeb, Morocco Application March 3, 1938, Serial No. 193,716In France April 23, 1937 1 Claim.

My invention relates to a can opener combined with a stopper and adispensing device; it permits of opening any ordinary can of the trade,of converting it instantly in a hermetically sealed dispensing canprovided with a stopper.

The drawing represents, by way of example, an embodiment of myinvention; in the various figures, like reference characters indicatecorresponding parts.

Fig. l is a perspective view of the complete device which consists of anopener, a fixing washer, a nut and a closing cap. Figure 2 is ahorizontal section through the opener; Figure 3 is a plan view of thefixing washer; Figures 4 and 5 are plan views on the top of the can,which is partly torn away. The opener consists of a screwthreaded tube afixed on a basis 21 of hardened steel plate which projects a number ofdepending teeth q, r, s, 15 provided with sharpened oblique cuttingedges and ending in a sharp point. The

' tube a. has a longitudinal groove cutting its screw thread. The washerhas an inwardly projected tooth h adapted to slide in groove 0 whenwasher f is engaged over tube a. A nut e and a cap (1 are adapted to bescrewed on tube a. The device is used as follows. The points q, 1', s, tare placed on the top of a can near the edge, in order that theprojection g of washer 1 cannot make a complete revolution round tubeat, its end contacting with the protruding edge any of the top of thecan, as shown by Figure 5. A blow on the cap (1 drives the points (1, r,s, t through the top of the can, the sharp edges of the teeth cuttinggradually the metal till a piece corresponding to i, 7', k, l iscompletely out out, whereupon the teeth enter the can. Now, tube a isturned about 45 on its axis; washer f is lowered till it rests on thetop of the can and afterwards turned till the end. of its projection.abuts the rim XY; screw e is screwed down to press upon washer f, 5 thussealing the can. Tube a can now serve as a pouring spout; after use, itcan be stoppered by screwing on cap (1.

An elastic joint may be placed under washer f to ensure better closure.The number of cut- 10 ting teeth is facultative. Tube (2 may be securedagainst rotation in any other way. The cutting teeth may be inclinedoutwards in order to facilitate the extraction of part 17 out of thecan. Nut e may be knurled, winged or pinned. When tube a is providedwith a laterally projecting spout which permits of holding the deviceagainst rotation, washer and slot 0 may be dispensed with, the nut ebeing then made large enough to cover the hole in the can. When the canhas 20 been emptied the device may be withdrawn to be used on anothercan.

Having now described my said invention and ascertained the manner inwhich it is to be performed, I declare that what I claim is:

In a can opener, the combination of a screwthreaded tube fixed upon abase provided with a number of depending teeth having sharp points andcutting edges, said tube having a longitudinal groove from end to end, awasher with an inner tooth adapted to slide in said groove after thewasher has been slipped over said tube, a nut and a cap adapted to bescrewed on said tube, substantially as described.
